Yes, I tried both PC Studio and New PC Studio. Neither one worked. I even went so far as to contact both AT&T Wirelss and Samsung for assistance. It wasn't until I spoke to Samsungs second level support staff that they admited there was no data syncing support on this particular phone. I've since returned the device back to AT&T for a full refund.

On the plus side I was eventually able to get my HTC Hermes / Cingular 8525 to work with my UConnect hands free kit in my Jeep by simply changing the devices name under the About option in the Control Panel. So one of my two major issues has been resolved.
